ICE-CREAM FREEZER.

.srncxmca'rronrormm part of Letters Pat t No. 605,606, dated June 14,1898.

' Application filed April 21, 1897.

Be it known that I, EDGAR O. HILL, a citizen of the United States,residing at Horse Cave, in the county of Hart and State of Kentucky,have invented certain new and use ful Improvements in Ice-CreamFreezers, of which the following is a specification, reference being hadtherein to the accompanying drawings.

This invention relates to certain" new and useful imp'rovementsinice-cream freezers.

My improvements relate to various featu res of construction andarrangement. Among them are a removable'cream vessel adapted to besecured to a non-removable ice-receptacle cover, so that 'access'm'ay behad to clean both it and the ice vessel, an ice-door in the head of theice vessel adapted when open to protect the cream vessel from thedrippings incident to inserting the'ice," a peculiar and efficientconstruction for adj listing the supporting-shaft relatively to'itssupporting bracket and which also permits the ice vessel to comedown and rest upon the base, and

to other details hereinafter described, and

particularly pointed out in the claims.

In the accompanying drawings, on which like reference-letters indicatecorresponding parts, Figure 1 is avertical sectional View of my improvedapparatus; Fig.- 2, a plan view thereof; Fig. 3, a horizontal sectionalview on the line as 0c, looking'downwardly; Fig.4, an enlarged verticalsection of a portion of the apparatus, and Fig. 5 adetail View of theyoke and supporting-sleeve.

The letter A designates a'base, and the letter'B a supporting-bracketsecured to the base and having flanges O,which stand apart enough toreceive between them the support-' ing-standard D, pivoted at E to thebracket and adapted to be held at different inclinations by a pin F,fittingeither of the series of holes G and held by a chain Hto preventbeing lost. A stop G prevents the standard D from getting out frombetween the flanges when the standard is in its uppermost position. Thestandard has a shoulder'I, upon which rests a thimble J, secured tothebottom of the ice vessel K and held by jam-nuts L.. This thimble isadapted to revolve upon the reduced portion M of the standard. A cup 0,as brass or some material not subject Serial No. 633,087. (Np model.)

to attack by the salt used with the ice, is screwed upon the thimble'J.This cup acts to make a tight joint with the tip Q, also of brass orsome material adapted to withstand the action of salt and carried by asleeve P, whose tight connection with the cream vessel R preventsleakage therefrom]. The upper end of the sleeve P is fitted to revolveon the hub of a yoke S, which yoke ismounted upon an angular portion Tof the standard, so as to remain stationary and in connection 'with thelower yoke U suspended by the rods V and held 'from lateral displacementby loosely fitting over the sleeve 1. To each of these yokes are pivotedarms W and X. The arms W carry a beater Y,'and the arms X carry ascraperZ.

On the rods V are mounted springs a a and b b, respectively. Theadjoining'en'dsof the springs a are secured to their rod V, so that thesprings act to hold the beater Y against the action of the cream, assuggested in Fig. 3, the springs permitting the beater to yield to thecurrent and force of the cream. The springs b at their adjoining endsarealso secured to their rod V, so that they will resist and yield tothe scraper Z in the opposite direction, as also suggested in Fig. 3.The

beater is beveled at c'on the side against which the cream acts, so thatit will yield away from the can and give a contracted outlet or passagefor the current of cream .between the beater and can. On the other.'hand, the scraper Z is beveled on the side away from the approachingcream, so that it will recede from the walls of the cream'vessel-andpermit the icyparticles 'which'it removes from the vessel to freelyescape through the inclined passage thus formed.

Referring to the upper end of the ice vessel, it will be seen that Ihavejprovided it with'a cover 6., secured to it in a stationary manner,and that the cream vessel is provided with an annular bead d, which fitsupon a gasket g, carried by the cover 6. Thus a tight joint is madebetween the cream vessel and such cover. To secure the cream vessel insuch position, I provide turn-buttons h, adapted to pass over inclinedlugs z','projecting from the cream vessel. By swinging the buttons toone side the cream vessel canbe removed, the tip Q'separated from thecup 0,

and the interior devices permitted to come out with the cream vessel.

In order to aerate the cream, which has the effect of making a betterproduct and of 1naking it lighter and not so compact, I provide a top jfor the cream vessel, perforated, as shown at 7;, to admit theatmospheric air to pass into the cream. A bail Zadapts the top to beremoved and replaced.

The ice vessel is provided at one side with a handle m and at the other,so as to balance it properly, with an ice-door 0, having clips q, hingedupon a rod 0', carried by the cover 0. Inclined surfaces 3 on theice-door are engaged by turn-buttons 2", so as to hold the door closed.XVhen the door is opened for the insertion of ice, it stands as a guardto prevent the drippings from the ice from getting over on the creamvessel and the joint between it and the cover 6. A drip-plug u isprovided at the bottom of the ice vessel. Thus it will be seen that inmy freezer I have provided for removing the cream vessel for the purposeof cleaning it and of giving access to the interior of the ice vesselfor the like purpose, also a peculiar arrangement of cream-beater at oneside and scraper at the other, which automatically yield to the force ofthe cream, and that these devices are beveled or have beveled surfaces,so that as to the beater a tapering channel is presented between it andthe wall of the vessel on the contact side of the beater, while as tothe scraper the tapering space permits the escape of the dislodged icyparticles, while the scraper will also yield to severer currents; also,that I am enabled to produce a superior product by reason of myperforated top,whieh permits of the aeration of the cream during theprocess of freezing. It will be observed also that the construction ofthe sleeve I, with its tip Q and the thimble J and its cup 0, permitsthe removal of the cream vessel. It will further be observed that I canfold my ice vessel down to and upon the base A for convenience inshipping and in placing the apparatus away when not in use. It will beunderstood, of course, that when the handle an is taken hold of the twovessels are revolved about the standing beater and scraper and thecentral standard.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

1. I11 an ice-cream freezer, the combination with a central standard,ofan ice vessel having a thimble provided with a cup, a non-removablecover for said ice vessel, a cream vessel removably secured to saidcover and having an interior beater and scraper and a sleeve having atip removably fitted into said cup whereby a tight but severable jointis formed so that the cream vessel may be removed.

2. In an ice-cream freezer, the combination with a centrally-shoulderedstandard, of an ice Vessel. having a thimble mounted on the standard andupon its shoulder, a cream vessel removably secured to the cover of theice vessel, a yoke on the upper end of the standard, a sleeve rotatablymounted in said yoke at one end and connected to the cream vessel at theother, a tight but separable joint between said thimble and sleevebetween the two vessels, a lower yoke on the sleeve and aspringcontrolled pivoted beater and scraper carried by said yoke.

3. In an icecream freezer, the combination with an ice vessel having acover and turnbuttons, of a cream vessel removably fitted in said coverand having inclined lugs projecting from the cream vessel for saidturnbuttons, and an annular body fitted upon a gasket carried by thecover.

4. In an ice-cream freezer, the combination with a base having a bracketprovided with separate wings, of a standard pivoted in the bracketbetween the said wings,the win g having a series of perforations, and apin to hold the standard in adjusted positions.

5. In an ice-cream freezer, the combination with a central standard, ofan ice vessel having a thimble extending through it, and a cup on thethimble with a conical mouth, of a cream vessel a sleeve secured theretoand a tip on the sleeve having a conical end fitted to the cup, saidcentral standard passing through said sleeve,'cup and thimblc,substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
